Ah yes, IKEA devices… IIRC, some of these don’t use the traditional Zigbee HA1.2 or 3.0 standards that are most popular amongst many of the Smart Home Hubs. I believe the IKEA Motion Sensor and Button devices use TouchLink, instead of traditional ZHA (somebody please correct me if I am wrong about this!) The IKEA devices seem to work most reliably when paired to an IKEA hub. The IKEA Bulbs and Outlets do seem to work well on most hubs, however their color bulbs don’t use the same color scheme as pretty much all other bulbs on the market.
BTW - there are numerous reports of battery life issues for the button controller when paired directly to a ST hub, for example
The other troublesome brand of Zigbee devices are the Xiaomi/Aqara devices. These are very challenging to keep connected to a standards-compliant Zigbee Home Automation (ZHA) controller (i.e. hub). They also perform best when paired to their own hub.
